11. alleles of the gene that determines seed coat patterns in lentils can be organized in a dominance series: marbled > spotted = dotted (codominant alleles) > clear. a lentil plant homozygous for the marbled seed coat pattern allele was crossed to one homozygous for the spotted pattern allele. in another cross, a homozygous dotted lentil plant was crossed to one homozygous for clear. an f1 plant from the first cross was then mated to an f1 plant from the second cross. a. what phenotypes in what proportions are expected from this mating between the two f1 types? b. what are the expected phenotypes of the f1 plants from the two original parental crosses?

Oxygen and hydrogen gas are at the same temperature t.what is the ratio of kinetic energies of oxygen molecule and hydrogen molecule if oxygen is 16 times heavier than hydrogen.

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)
